Multi-Function PCM CODEC
This version: Aug. 1998
MSM7502
Previous version: Nov. 1996
GENERAL DESCRIPTION
The MSM7502, developed especially for low-power and multi-function applications in touch-
tone telephone sets and digital telephone terminals of digital PBXs, is a single +5 V power supply
CODEC device. The device consists of the analog speech paths directly connectable to a handset,
the calling circuit directly connectable to a piezosounder, the push-button key scanning interface
between push buttons and control processors, the dial tone generator, the
m-law/A-law
CODEC,
and the processor interface. The functions can be controlled via 8-bit data bus.
For the CODEC of the MSM7502, an MSM7543 is used as a core CODEC, so the MSM7502
provides the available bit clock range wider than the family product MSM6895.
In addition, the MSM7502 performs the greater key interface function and offers the upgraded
side-tone level, receive level, and speaker pre-amplifier output level.
